Abstract: 1,063,679. Transformers. WESTINGHOUSE ELECTRIC CORPORATION. Oct. 7, 1965 [Oct. 23, 1964], No. 42607/65. Heading HIT. A transformer with insulated aluminium or copper foil strip or wire windings has its core formed from wound magnetic Si-Fe strip coated with an electrically insulating inorganic, vitreous, glass-like material which also bonds them together, and the core and windings are encapsulated in an insulating impervious material comprising a cured thermosetting resin of the epoxy, polyester, or silicon type plus at least one finely divided, inorganic, non-friable, inert filler such as silica, silicates, alumina, porcelain, mica, glass and other fillers listed in the Specification plus possibly platicizers. Glass compositions are listed in the Specification. Before applying the vitreous material, the magnetic strip is plated with a metal barrier layer, e.g. Ni, Al, to keep the vitreous material free from contaminants such as iron oxide. The vitreous material is then applied by dipping, rolling, or spraying and is fused to the magnetic strip in a furnace. The strip is then wound and placed in a furnace to anneal the core during which process the winding stresses are relieved and the vitreous material softens. Upon cooling, the vitreous material solidifies to bond the laminations together, and since the coefficient of expansion of the vitreous material is less than that of the magnetic strip, the vitreous material is placed under compression and the strip under tension, the latter reducing core noise due to magnetostriction. The encapsulated apparatus may be enclosed in a fluid-filled casing.
